The Observation and Research for Morphology and Microstructure of Pyrite Whiskers Synthesized by Hydrothermal Process

Abstract:

Morphology and micro-structure of the pyrite whiskers synthesized by hydrothermal process were systematically observed by using transmission electron microscope. The results indicated that whiskers revealed various morphologies, including smooth, rough and branched. Combined with the hydrothermal reaction conditions, the causes of whiskers morphology diversity is: straight smooth whiskers grow in the condition of stable concentration, temperature, and interface state; whiskers with rough surface and complex morphology grow in the condition of unstable concentration, temperature, and interface state; the same level branching structure rotation was the result of hydrothermal disturbance; nano-crystalline grains formed after the main growth of the whiskers.
